Every AI button first checks your wallet balance in the browser. If it is below $0.07 (or below the feature's own fee, e.g. $0.03 for the random menu, $1.75 for the retail stock upload, or $0.07 x the number of ingredients for receipt macros) you get the pop-up You are out of AI Credits – To use this feature you must purchase AI credits with Cancel and Purchase Credits buttons. Click Purchase Credits to open the AI Wallet, add credit, then return and try again. If the server-side check fails instead you see the message API Error: Not Enough Credits Please Refill. Turning on Auto Recharge prevents this from recurring.
